About the RUFORUM 2010 Biennal Conference
"The 2010 RUFORUM Biennial Conference was the second in the series. The main objective of the Biennial conferences is to provide a platform for agricultural research for development stakeholders in Africa and beyond to actively exchange findings and experiences, while at the same time learning lessons towards improving performance of the agricultural sector and ultimately people’s livelihoods. The biennial conference is RUFORUM’s most comprehensive meeting for the diversity of stakeholders in agriculture. It is especially dedicated to graduate students and their supervisors, grantees in RUFORUM member universities and alumni. It is a platform for peer review, quality control, mentorship, networking and shared learning. This record contains an extended abstract accepted under the theme of Natural Resource Management"
Development of aluminium toxicity tolerance system for sorghum in agro ecological region three of Zambia
Abstract:
The overall objective of this study was to characterize selected
sorghum varieties for Aluminium (Al) tolerance. The specific
objectives were to determine performance of selected sorghum
varieties grown in Al prone environments, identify root
characteristics associated with Al tolerance and to develop a
selection criterion for Al tolerance in sorghum.Twenty sorghum
genotypes were evaluated in the field at three sites with high
soil Al levels and in the laboratory for aluminium tolerance were
characterized. Based on the results obtained in the laboratory
and field analysis, the top 10 entries that showed Al toxicity
tolerance and high grain yield were entries 1,2,3,6,8, 11, 12, 16,
17 and 20. Among these, the top seven in the laboratory analysis
were entries 2, 3, 12, II, 17, 16 and 20. The top seven in the
field analysis were entries 1, 6, 8, II, 17, 16 and 20. Therefore
the best perfomers in both the laboratory and field analysis
were entries 11, 17, 16 and 20 score.
L’objectif global de cette étude était de caractériser des variétés
choisies de sorgho pour la tolérance en aluminium (Al). Les
objectifs spécifiques étaient de déterminer la performance des
variétés choisies de sorgho développées dans les
environnements enclins d’Al, identifier les caractéristiques de
la racine liées à la tolérance en Al et d’élaborer un critère de
choix pour la tolérance en Al dans le sorgho. Vingt génotypes
de sorgho ont été évalués sur terrain à trois emplacements avec
les niveaux élevés d’Al du sol. Dans le laboratoire, ils ont été
caractérisés pour la tolérance en aluminium. Basées sur les
résultats obtenus en analyse de laboratoire et sur terrain, les 10
entrées principales qui ont montré la tolérance de toxicité d’Al
et le rendement élevé de grain étaient les entrées 1, 2, 3, 6,8,
11, 12, 16, 17 et 20. Parmi ces dernières, les sept principales
dans l’analyse de laboratoire étaient les entrées 2, 3, 12, II, 17,
16 et 20. Les sept principales dans l’analyse sur terrain étaient
les entrées 1, 6, 8, II, 17, 16 et 20. Par conséquent, les plus performantes dans l’analyse de laboratoire et celle sur terrain
étaient les entrées 11, 17, 16 et 20.
